Just would like to know where I'm puttin' the seafoam at:

What are you trying to do exactly? To clean the inside of your engines you pour it with your oil run it for 10-15 min and DO AN OIL CHANGE. To clean your injectors you pour the bottle into your gas tank and FILL the tank up with Gas. If your trying to pour it directly into your intake manifold you get a Carb / engine Starter Spray.

I did one in the gas. I don't wanna do it in the oil right now, cuz I just changed it like 300miles ago. As for the intake manifold, I've seen it done on youtube, where they pour it in a PCV or whatever. And I was just wondering which one to pull off to pour it down, cuz there are two connected to my intake.

Your gonna wanna use one of the ones that go into the intake manifold after the throttlebody.
There are 3 on top of the throttle body, you can use whichever one has vacume.
You will hold the throttle open a little bit so that the engine will suck in the seafoam without dying, once the bottle is empty let the car die, and start it back up 15 minutes later or so, and enjoy the smokescreen. Lol
you will need to change your oil after because it will thin it out some.

this is forced induction how?

You know, you force the engine to induce the seafoam!

Or you can use Tranny Fluid. At least that is how it was done back in the day.

that stuff sounds a lil bit strong to use. but some had great results but donno if there were short or long term side effects.

What he said lol.

Basically put 1/3 of the can in your gas, 1/3 in the oil, and pull a vacuum line off of the throttle body (make sure it has vacuum while the motor idles) and stick it down in the bottle. It will suck the liquid into the motor, and as soon as it's done shut the car off (easier to have a friend in the car, they can help rev the motor to keep from dying and they can shut it off).

Let the car sit 15 minutes, 1 hour, however long you like, then start it up and let it idle, DON'T take it for a drive or rev it up a lot. It will smoke like CRAZY for anywhere from 10-30 minutes while it burns off the seafoam you sucked into the motor. I find this a good time to check for exhaust leaks if you happen to have any, because the smoke will come out from any hole in the exhaust. Now before you drive it, change the oil and filter. I usually change plugs after doing it, but that's also because I make this part of the 100k maintenance.

Depending on what kind of shape your motor is in, you may notice a difference in performance and mileage, you may not. My Miata felt like a whole new car after seafoam, and it only had 100k on it. My hatch was a little noticeable (with 150k), mostly in gas mileage, and my old 'vert didn't change at all.

if you really want to do it theres vids all over youtube
